AUTOMATIC ROCKING COT.

SPECIFICATION forming part of Letters Patent No. 418,093, dated December24, 1889.

Application filed May 9,1889. Serial No. 310,128. (No model.) Patentedin England November 2, 1888, No. 15,881.

To all whom it may concern:

Be it known that 1, Aims WAlNWR-IGHT, a subject of the Queen of GreatBritain, residing at Sheifield Road, Barnsley, in the county of York,England, have invented certain new and useful Improvements in AutomaticRocking Cots, (for which I have obtained Letters Patent in England,No.15,831, dated N ovember 2, 1888;) and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates to that type of cribs, cradles, or similarstructures which are suspended by pivoted hangers operated by clockworkto rock or oscillate the crib or cradle.

The object of my invention is to improve the connecting mechanismbetween the crank or drive Wheel of the clock-work and the cot, cradle,or other object to be rocked, whereby the return strokes or motions arerelieved from jerks and suddenness by a flat springarm, which alsoassists in driving the cot or cradle by overcoming the tendency of thedriving mechanism to stop when the crank or drive wheel is on thedead-center.

The object of my invention I accomplish by the construction andcombination of devices hereinafter described and claimed, referencebeing made to the accompanying drawings, in which Figure 1 is a sideelevation of a rocking cot or cradle embodying my invention. Fig. 2 isan end elevation of the same, and Fig. 3 is a detail view of the slottedhanger-bar,

showing its connection with the crank or drive wheel of the clock-work.

In order to enable those skilled in the art to make and use myinvention, I will now describe the same in detail, referring to thedrawings, wherein- The letter Aindicates a cot, cradle, or similarobject which is to be rocked or oscillated, and B 13 indicate twohanger-bars secured at their lower ends to the cot or cradle and attheir upper ends suspended by knife-edge or similar pivots 0, attachedto the top portion of a stationary frame-work D of any suitableconstruction. A casing N, secured to the framework adjacent to one ofthe hanger bars, is provided with clock-Work of any suitableconstruction, such as is usually adopted for rocking or oscillatingcradles. .As the clock=work may be of any known type driven by a springor Weight, I do not deem it nec essary to illustrate any more thereofthan the crank or drive wheel M, which is mounted on a shaft extendinginto the casing N to be revolved by the clock-work therein. A pitman His connected at one end with the crank or drive wheel to be reciprocatedby the rotation of the latter, and to the opposite end of the pitman isconnected the lower end of a fiat spring-arm G, carrying at its upperend a stud F, which is adapted to work in a longitudinal slot E,provided in the hanger-bar nearest the clock-work casing. I have showntwo similar slots E in the hanger-bar, as this permits the crank ordrive wheel to be located at either side of the frame-work; but,obviously, a single slot may be employed, its purpose being to permitthe stud F to correctly work therein as the hanger-bar oscillates on thepivot C. The revolution of the crank or drive wheel reciprocates thepitman, which, through the fiat spring-arm, oscillates the hanger-barand swings the cot, cradle, or similar suspended article. The spring-armyieldingly breaks the suddenness of the return strokes or motions andavoids jerking of the cot or cradle, and such yielding spring-arm by itsresiliency also overcomes the tendency of the crank or drive wheel tocease revolving when on the dead-center.

The bottom of the cot or cradle may be provided with a pendent rod orprojection L to work in a stationary slotted plate J, as usual, tosteady the cot or cradle in its oscillations.

I do not broadly claim oscillating a cradle a pitman H, connected at oneend to the I of thecrank or drive wheel to stop on the crank or driveWheel and reciprocated theredead-center, substantially as described.
